NOTE C -- DISCONTINUED OPERATIONS

In June 1999, the Company made the decision to discontinue the denim and
industrial yarn operations which were unprofitable in recent years. These
operations have been treated as discontinued operations in the thirteen week
consolidated financial statements.

The Company finalized its estimate of the impact of its discontinued operations
on its employee benefit plans. The curtailment income of approximately $518,000
resulting from the discontinued operations is reflected in the results of
discontinued operations for the thirteen week period ended September 30, 2000.

The results of operations for the denim and industrial yarn businesses have been
classified as income (loss) from discontinued operations as follows:

NOTE E -- SEGMENT INFORMATION

The Company has two reportable segments in its continuing operations: Consumer
Products and Apparel Fabrics. Each reportable segment is organized around
product similarities. The Consumer Products segment manufactures and sells a
complete line of muslin, percale and premium threadcount products for the
bedroom, including fashion-coordinated bedding sets and comforters marketed
under the Thomaston label, and offers home furnishing fabrics for sale to other
manufacturers of home furnishings. The Apparel Fabrics line is directed toward
dyeing and finishing heavier fabrics such as twill and other value-added
fabrics.

The profit performance measure for the Company's segments is defined as Internal
EBIT (earnings before interest and taxes). The aggregate of Internal EBIT for
the reportable segments differs from the Company's consolidated earnings before
interest and taxes by costs that are deemed to be non-operating in nature.

Allocations of corporate general and administrative expenses are used in the
determination of segment profit performance.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

In the fourth quarter of fiscal 1999, the Company began a comprehensive
restructuring of its operations and businesses with a view towards enhancing and
focusing on the Company's operations which are believed to present the best
future profitability and growth potential. As a result of completing the
assessment of various strategic alternatives, the Company concluded that
discontinuing the Company's denim and industrial yarn operations, which were
unprofitable in recent years, was in the best interest of the Company. In
conjunction with the exit of these businesses, the Company's balance sheet at
September 30, 2000 includes assets held for sale in the amount of $4,280,000.
Any proceeds from the sale of these assets will be applied against outstanding
term loan obligations.

The Company has concluded that it will focus on the manufacturing and marketing
of home furnishings as well as dyeing and finishing fabrics for casual and
career apparel. The Company believes that these operations offer the most viable
opportunity for improving future profitability. The Company completed a
personnel and operational realignment of these businesses which it believes will
improve their future profit margins.

RESULTS OF OPERATIONS

Sales from continuing operations for the first fiscal quarter ended September
30, 2000 were down 10% to $36,633,000 from first quarter sales last year of
$40,724,000. Sales in the Company's Consumer Products area were down as a result
of fewer orders being called out by the Company's retail customers. A weakness
in the demand for lighter-weight apparel fabrics and commission finishing also
contributed to the sales decline.

Cost of sales for the quarter just ended increased to 95.5% of sales compared to
89% of sales for the quarter ended October 2, 1999. During the first quarter of
fiscal year 2001, the Company selectively idled certain manufacturing facilities
in order to better match inventory levels with orders. This slowdown of
manufacturing resulted in decreased manufacturing capacity utilization and plant
productivity. Raw material prices have also increased during the quarter ended
September 30, 2000 as compared to raw material prices during the first quarter
of fiscal year 2000.

Gross profit for the first quarter of fiscal year 2001 was 4.5% of sales as
compared to 11% of sales for the first quarter of last year.

Selling, general and administrative expenses decreased to $3,386,000 from
$4,057,000 for the first quarter of last year. The Company's realignment of its
operations, which began in the fourth quarter of fiscal year 1999, has resulted
in reductions in certain selling, general and administrative expenses.
Improvements have also been realized in the cost of bringing new product samples
to the market.

Other income (net) for the quarter ended September 30, 2000 was $35,000 compared
to $116,000 for the comparable period last year. Other income related to
miscellaneous equipment sales, royalties and interest earned on the Company's
short-term investments of cash.

Interest expense and amortization of credit agreement fees increased from
$2,142,000 during first quarter of fiscal year 2000 to $2,305,000 during first
quarter fiscal year 2001. The increase was the result of higher interest rates
and fees under the Company's various credit agreements. Total debt at September
30, 2000 was $61,655,000, down $8,523,000 from total debt at October 2, 1999 of
$70,178,000.

The Company has not recorded an income tax benefit as a result of its operating
loss carry forward position.

For the first quarter of fiscal year 2001, the Company sustained a loss from
continuing operations of $4,024,000 , or $ .62 per basic and diluted share, as
compared to a loss of $1,584,000, or $0.24 per basic and diluted share for the
first quarter of fiscal year 2000.

Discontinued operations income was $421,000 for the first quarter of 2001 and
included curtailment income from its employee benefit plans. The Company
recognized curtailment income of approximately $518,000. This income resulted
from finalizing the calculations of the impact of the terminated employees from
discontinued operations upon the benefit plans obligations.

LIQUIDITY AND CAPITAL RESOURCES

Operating activities provided cash of $7,538,000 for the quarter ended September
30, 2000 and $3,539,000 for the quarter ended October 2, 1999. Net cash used in
investing activities amounted to $875,000 in capital expenditures in the first
quarter of fiscal year 2001 compared to $562,000 in capital expenditures in the
first quarter of fiscal year 2000. During the first quarter of fiscal year 2001,
financing activities used cash of $6,997,000 as a result of net repayments of
indebtedness. During first quarter of fiscal year 2000, the financing activities
used cash in the amount of $615,000.

The Company's Loan and Security Agreement (the Loan Agreement) provides for
borrowing as follows:

-        Revolving advances equal to the lesser of $70,000,000 or a specified
         percentage of certain accounts receivable and inventory as defined in
         the Loan Agreement. At September 30, 2000, $28,280,000 was outstanding
         and $1,996,000 was available for borrowing under the revolving advances
         provisions. The revolving advances bear interest at the Reference Rate
         plus 1% or the Euro-dollar Rate plus 3.25%. The revolving advances are
         payable on July 27, 2004, and provide for an early termination penalty
         as specified in the Loan Agreement.

-        Tranche A Term Loan of $20,000,000 is payable in monthly installments
         of $333,333 through July 27, 2004 and bears interest at the Reference
         Rate plus 1.75% or the Euro-dollar Rate plus 3.75%.

-        Tranche B Term Loan of $5,000,000 is due July 27, 2004 and bears
         interest at 18.5% of which 15% is payable currently and 3.5% per annum
         is payable on the maturity date.

Borrowings under this Loan Agreement were used to reduce the existing Credit and
Security Agreement to $15,000,000 as discussed below and to repay the senior
notes payable and industrial revenue bonds.

On July 27, 1999, the Company entered into an Amended and Restated Credit and
Security Agreement (the Credit Agreement) which reduced the existing borrowings
under the previous Credit and Security Agreement to $15,000,000. Interest is
accrued at a rate of 15% increasing at the rate of 1% per month to a rate of 20%
effective January 1, 2000. Interest is payable monthly at the Euro-dollar Rate
plus 3.5% or the Base Rate plus 1.5%. The difference in the interest accrued and
the interest paid is added to the balance of the borrowings. Borrowings under
the Credit Agreement are due July 27, 2004 unless repaid prior to that date.

On May 31, 2000, the Company entered into a Promissory Note with a bank in the
amount of $10,000,000. Interest is paid monthly at a rate equal to the Prime
Rate plus 1.5%. Borrowings under the Promissory Note are payable monthly
beginning July 1, 2000 through May 31, 2020, unless repaid prior to that date.
Borrowings under this Promissory Note were used to reduce the amount outstanding
under the Credit Agreement by $9,043,000 and to repay $525,000 of the balance
outstanding under the Loan Agreement.

Borrowings under the Loan Agreement and Credit Agreement and Promissory Note are
secured by all assets and properties of the Company. The Loan Agreement, the
Credit Agreement and the Promissory Note contain various restrictions relating
to, among other things, maintaining a certain level of tangible net worth, a
minimum current ratio, a minimum debt to equity ratio, attainment of certain
amounts of earnings before interest, taxes, depreciation and amortization and
restrictions on capital expenditures.

On September 12, 2000, the Company obtained waivers for certain financial
covenants as to which the Company was not in compliance as of May 31, 2000 and
July 1, 2000. On September 12, 2000, the Company also obtained an amendment that
established certain financial covenants covering the period ending June 30,
2001. At September 30, 2000, the Company was in compliance with these financial
covenants. The Company is subject to changing business and economic conditions
(many of which are beyond the Company's control), including a general
deterioration in the domestic textile industry, which may affect its ability to
comply with the covenants in the near term and there can be no assurance of such
compliance. If the Company is unable to comply with these covenants, there can
be no assurance that the Company's creditors will provide any additional waivers
or amendments with respect to any such non-compliance.

A breach of any of the covenants contained in the Company's Loan Agreement,
Credit Agreement or Promissory Note could result in a default or event of
default under the terms of these credit facilities. Upon the occurrence of an
event of default, the Company's lenders would not be obligated to make
additional advances under the credit facility that is in default; would be
entitled to declare all amounts outstanding under the credit facilities in
default, including accrued interest or other obligations, to be immediately due
and payable; would have the rights to block payment on substantially all of the
Company's other long-term debt; would be entitled to proceed against the
collateral granted to them to secure the applicable debt. In these
circumstances, cross defaults could occur making

<PAGE>   11

substantially all of the Company's other long-term debt due, in which event the
Company cannot be certain that its assets would be sufficient to repay in full
all of its long-term debt.

As a result of the covenants described above, the Company's ability to respond
to changing business and economic conditions and to secure additional financing,
if needed, is significantly restricted.

Based upon current and anticipated levels of operations, management anticipates
that its cash flow from operations, together with amounts available under its
current borrowings, will be adequate to meet its anticipated cash requirements
in the foreseeable future. However, the Company's cash requirements during the
month of December are traditionally higher than those of other months due to
various factors, including the payment of vacation and holiday payrolls and the
payment of property taxes. The Company also expects a continuing slowdown in the
retail market during the December quarter. In the event that cash flows and
available borrowings are not sufficient to meet future cash requirements, the
Company may be required to seek additional or alternative financing. There can
be no assurances that additional financing would be available or, if available,
offered on terms acceptable to the Company.


WARRANTS TO LENDERS

The Company has issued warrants to its lenders in connection with the Credit
Agreement. The warrants permit the lenders to purchase Class A and Class B
common shares of the Company for nominal consideration. The warrants are
currently exercisable and may be exercised through December 31, 2004. Although
the lenders have not indicated to the Company that they intend to exercise the
warrants, if they elect to exercise all of their warrants, the lenders would
receive an interest equal to 10% of the outstanding equity of the Company in
each class, on a fully diluted basis.

ASSETS HELD FOR SALE

The Company's management intends to utilize the proceeds from the sale of the
assets held for sale to reduce outstanding term loan obligations. Management
believes, based on current appraisals, that $5,431,000 could be realized from
the sale of these assets, including $4,280,000 from the assets related to
discontinued operations. However, actual results could differ significantly from
these estimates. In October 2000, the Company completed the sale of its Pike
facility with the proceeds of approximately $1.4 million being used to reduce
the amount outstanding under the Credit Agreement.

INVENTORIES

Inventories at September 30, 2000 and October 2, 1999 were $34,049,000 and
$34,837,000, respectively. Total inventory turns on an average annualized rate
were 4.1 times for first quarter 2001 and 4.2 times for first quarter 2000.

NEW ACCOUNTING STANDARDS

The Company has adopted Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and for Hedging Activities," effective in the first
quarter of fiscal year 2001. The adoption of SFAS No. 133 did not affect results
of operations or financial position.

RAW MATERIALS

The Company's primary raw material is cotton. As a commodity, cotton is traded
on established markets and periodically experiences price fluctuations. The
Company monitors the cotton market and buys its cotton from brokers. The Company
has not had and does not currently anticipate any difficulty in obtaining
cotton.

In order to assure a continuous supply of cotton, the Company enters into cotton
purchase contracts for several months in advance of delivery which either
provide for (1) fixed quantities to be purchased at a pre-determined price or
(2) fixed quantities to be purchased at a price to be determined (at a later
date). When the Company sells its product to its customers, the cost of cotton
under existing cotton purchase contracts is taken into account in calculating
the price for the Company's product. The Company generally attempts to match
product sales contracts with fixed price cotton purchase contracts and uses
market price cotton contracts to anticipate future needs and subsequent product
sales contracts. To the extent prices are sometimes fixed in advance of
shipment, the Company may benefit from its cotton purchase contracts to the
extent prices thereafter rise, or incur increased cost to the extent prices
thereafter fall.

INTERNATIONAL TRADE

In December 1993, 117 countries reached an agreement under the General Agreement
on Tariffs and Trade (GATT) that would cover new areas of trade, further cut
tariffs and strengthen multilateral free-trade rules by creating a World Trade
Organization (WTO) as its successor. This agreement was ratified by the United
States Congress and went into effect on July 1, 1995. As part of this new
agreement, the Multifiber Arrangement (MFA) under which textile and apparel
trade had been controlled, will be phased out along with its import quotas over
a 10-year period. Tariffs on textiles will be cut by an average of 11.6% over 10
years. Under the agreement, quotas on the least sensitive import products will
be phased out over the first five years and quotas on the most sensitive import
products will not be affected until the latter part of the ten-year period.

The WTO agreement contains some provisions which may have a favorable impact on
the textile industry. An assembly rule of origin amendment makes it illegal for
a non-WTO member country to assemble garments from pieces cut in a member
country and then export the garments as originating in the country where they
were cut. Additionally, the agreement preserves the authority of the President
of the United States to control imports from non-WTO countries such as Taiwan or
China. China is currently negotiating its membership application with the WTO,
and if the application is accepted and China is admitted to the WTO, the Chinese
market share of apparel imports is expected to increase significantly over the
phase-in period.

Although the WTO agreement may reduce the cost of certain imported textiles, the
Company believes that upgraded technology resulting in increased productivity
and lower costs will enable it to compete in a global market.

The recently enacted amendment to the Caribbean Basin Economic Recovery Act
accords, for a specified transition period, the same preferential tariff and
quota treatment given certain textile and apparel articles imported from North
American Free Trade Agreement (NAFTA) countries to such articles that are
imported from certain Caribbean countries. In order to qualify for the
preferential tariff and quota treatment, however, apparel goods that are shipped
back to the United States must be sewn in eligible Caribbean countries using U.
S. yarn and fabrics. The Company believes that this new legislation will allow
it to compete favorably with Asian countries for market share in the apparel
area.

RECENT DEVELOPMENTS

The Company's Class A Common Stock has not maintained the minimum bid price
criteria set forth by the Marketplace Rules of the Nasdaq SmallCap Market (the
"Rules"), and the Company's Class B Common Stock has not maintained the minimum
market value of public float criteria set forth by the Rules. As a result, The
Nasdaq Stock Market ("Nasdaq") has informed the Company that if the Company is
unable to regain compliance with the Rules on or before November 16, 2000, each
of the Company's Class A or Class B Common Stock which continues to be in
non-compliance as of that date will be delisted at the opening of business on
November 20, 2000. As the trading prices of the Company's Class A and Class B
Common Stock are beyond the Company's control, the Company cannot assure that
either of its Class A or Class B Common Stock will be able to regain compliance
with the Rules prior to the deadline set forth by Nasdaq. If the Company's
Common Stock is delisted from the Nasdaq SmallCap Market, the Company's shares
will no longer be traded on the SmallCap Market, but will instead be traded on
the over-the-counter bulletin board system.
